i have developed a .wsp package and i got the access to the server(application server) to deploy it.. when i deployed the package and i try to access the site i was getting the error Service Unavailable(HTTP ERROR 503) .. when talk with admin earlier today he said that all application pools were stopped and he started them again, so when i accessed the site it was working again... now i again deployed it the same thing happen, (admin has left for the day)..since i have access to the server..i think the same thing must have happen ..any suggestion as to where can i go and find these application pools and start them again


The application pools are on the servers themselves. Since you are deploying WSP files I assume you are already remoting into the server. You have to open up IIS manager which will allow you to start the application pools.

IIS7 - http://technet.microsoft.com/en-us/library/cc732742%28WS.10%29.aspx

You may also want to view the sites and make sure that all SharePoint related sites are started as well. These will also be in IIS manager.

    I'd also inspect the IIS and ULS logs on the servers, as something is stopping the application pools from restarting when the WSP is deployed.

The root cause should be of interest to you too. I suggest that you read a post by Waldek on Optimizing the deployment process
